Beautiful issue condition with the serial (register) number annotated in ink on the obverse.
The only cash pattern known to us, a set of which consisted of two banknotes. The first with the numbers 1 through 6 shown in the numerator and the second with the numbers 789000.
The second part with the digits from 7 shown is usually found on the collector's market. The first one (like this one) is definitely rarer.
